Given numbers are 853, 396, 581, 990

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(853, 396) = 337788

GCD(853, 396) = ( 853 x 396 ) / 337788

= 853 / 396

= 853

Step2:

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

= 1 / 581

= 1

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 853, 396, 581, 990 is 1
